# Simple algorithm to count
# number of occurrences of (n) in (ar)

# Sudo: Algorithm
#     each time (n) is found in (ar)
#     (count) varible in incremented (by 1)

# I've put spaces to separate different 
# stages of algorithms for easy understanding
# however isn't a good practise

def count(ar, n):
    count = 0

    for element in ar:
        # More complex condition could be 
        # => (not element != n)
        if element == n:
            count += 1

    return count

# Testing
# add your test cases in list below
test_cases = [([1, 1, 2, 3, 5, 8, 13, 21, 1], 1), ("Captain America", "a")]
for test_case in test_cases:
    print("TestCase: {}, {}".format(test_case[0], test_case[1]))
    print("Results: {}\n".format(count(test_case[0], test_case[1])))

# You can add condition to check weather output is correct
# or not
